I am a masters of science student at well known university in Chicago. I am very interested in the confidential results of those who silence Myostatin for muscle growth. It sounds like you might be interested too. I would love to communicate with you if you should determine to go forward with your plan. I will not give medical, legal, scientific, or moral advice, but I can suggest reading material for your review and hypothetical postulations.
For example, the way in which you choose to silence myostatin will make a difference in the dose. There are two ways one could currently silence ystatin in vivo: (1) via RNA-interference of myostatin; (2) by the introduction of anti-myostatin antibodies.
Acceleron Pharma tested anti-myostatin antibodies in 1 mg and 3 mg doses on humans and found that it was well tolerated. It is unlikely that you will be able to get your hands on the exact antibody formulation used by Acceleron, but almost any lab can formulate something similar.
